Abstract

Mapping a knowledge domain in the interdisciplinary field of Social Memory is discussed, considering the linguistic materiality and the conceptual relations that are most appropriate to its representation. Theoretical instruments for knowledge organization in the field of information as well as of memory are both central in contemporary social studies and they must help a clear representation of a domain, especially when it lies in disciplinary frontiers. Two perspectives were used as methodological procedures: the conceptual analysis regarding the categorization of the authors' intellectual production selected from syllabus of the discipline Social Memory and Institution; and discursive fragments selected from Paul Ricour's text memory and imagination . As main results, data analysis from the first corpus pointed out six main facets that organize the memory context; and the second corpus, related to discursive materiality, organizes Ricour's ideas of memory from some philosophical points of view. As conclusions, we consider that mapping key concepts and discourses towards the main categories (ontological) and towards a group of relations derived from the discursive analysis process has enabled a possible framework for social memory indexing/searching studies. Even though this proposal is specific to a topic in a teaching program, it indicates a promising path for upcoming studies in Knowledge Organization.

Abstract

The proliferation of digital knowledge repositories (DKRs) used for distributed and collocated work raises important questions about how to manage these technologies. This study investigates why individuals contribute information to DKRs by applying and extending transactive memory theory. Data from knowledge workers (N = 208) nested in work groups (J = 17) located in Europe and the United States revealed, consistent with transactive memory theory, that perceptions of experts' retrieval of information were positively related to the likelihood of information provision to DKRs. The relationship between experts' perceptions of retrieval and information provision varied from group to group, and cross-level interactions indicated that trust in how the information would be used and the interdependence of tasks within groups could explain that variation. Furthermore, information provision to DKRs was related to communication networks in ways consistent with theorizing regarding the formation of transactive memory systems. Implications for theory and practice are discussed, emphasizing the utility of multilevel approaches for conceptualizing and modeling why individuals provide information to DKRs.

Abstract

A taxonomy is being developed to organize the content of a cultural heritage portal called Singapore Memory Portal, that provides access to a collection of memory postings about Singapore's history, culture, society, life/lifestyle and landscape/architecture. The taxonomy is divided into an upper-level taxonomy to support user browsing of topics, and a lower-level taxonomy to represent the types of information available on specific topics, to support user learning and information synthesis. The initial version of the upper-level taxonomy was developed based on potential users' expectations of the content coverage of the portal. The categories are centered on the themes of daily life/lifestyle, historically significant events, disasters and crises, festivals, a variety of cultural elements and national issues. The lower-level taxonomy was derived from attributes and relations extracted from essays and mindmaps produced by coders after reading memory postings for a sample of topics.

Abstract

The common core activity for digital humanities and memory institutions such as libraries, archives, and museums is digitizing the representations of cultural and historical documents, images, and artifacts. Most of these resources are delivered online to users. The emergence of Digital Libraries in the early 1990s was a turning point and a critical component of the world-wide shift to networked information. This article focuses on the fundamental role of Knowledge Organization Systems (KOS) for the Humanities with a special attention to libraries as one of the actors of Digital Humanities. The interplay between Digital Libraries and Digital Humanities will be highlighted. Not only will they provide access to a host of source materials that humanists need in order to do their work, but Digital Libraries will also enable new forms of research that were difficult or impossible to undertake before.

Abstract

This paper proposes a diffusion model to measure the evolution of stakeholders' disaster perceptions by integrating a disaster message model, a stakeholder model, and a stakeholder memory model, which collectively describe the process of information flow. Simulation results show that the rate of forgetting has a significantly negative effect on stakeholders' perceptions and the incremental increase in the number of affected individuals has a positive effect on the maximum level of stakeholders' perceptions, but negative effect on the duration of stakeholders' perceptions. Additionally, a delay effect, a stagnation effect, and a cumulative effect exist in the evolution of stakeholders' perceptions. There is a spike at the beginning of the profile of stakeholders' perceptions in the Damped Exponential Model. An empirical test supports the validity of this model of stakeholders' disaster perceptions.

Abstract

Purpose - The purpose of this paper is to examine how keeping the records of social networking sites (SNS) communication for secondary analysis institutes a new type of memory practice, one that seeks both to capture shared public memories and form new cultural understandings. Design/methodology/approach - Using a framework of documentary and memory practices the study conducts a qualitative content analysis of SNS communications collected from Facebook, GooglePlus and Twitter during a national event. It combines a content analysis of the communications with the analysis of their materiality and form to investigate potential contributions of SNS to social and cultural memory including their subsequent custodianship. Findings - The study finds that the message architecture and metadata of different social networks is comparable and collectively evidences differing aspects of social events to document their unique discourse. Findings demonstrate the contribution SNS is making to social memory and a framework for understanding how SNS in being incorporated into cultural memory practice is presented. Originality/value - This is one of the few studies that analyses a range of messages from differing SNS in order to understand their impact on cultural memory and the documentary practices of memory institutions.

Abstract

Employees in distributed organizations often engage in virtual work arrangements to accomplish day-to-day tasks. In turn, a lack of physical cues, challenges in establishing common ground with others and reduced face-to-face interaction each has the potential to hinder communication within an organization. Large multinational organizations may rely on transactive memory systems as a means of sharing knowledge and helping employees to accomplish day-to-day tasks. Research demonstrates that new information communication technology facilitates the development of transactive memory systems, but the role of transactive memory in virtual work arrangements is less studied. This article explores how dimensions of virtual work impact transactive memory systems. Data were collected from a large multinational organization that provides technology consulting services. Findings from this study demonstrate a clear relationship between the formation of transactive memory systems and the degree of geographic dispersion of employees. Moreover, the formation of transactive memory systems is negatively impacted by the diversity of teams' job functions. The use of internal information communication technology plays a positive role in influencing organizational memory when teams are geographically and functionally diverse. The results provide insight into how organizations can better utilize transactive memory systems to improve communication in virtual settings.

Abstract

Purpose - This study intends to identify factors that affect relevance judgment of retrieved information as part of the 2007 TREC Legal track interactive task. Design/methodology/approach - Data were gathered and analyzed from the participants of the 2007 TREC Legal track interactive task using a questionnaire which includes not only a list of 80 relevance factors identified in prior research, but also a space for expressing their thoughts on relevance judgment in the process. Findings - This study finds that topicality remains a primary criterion, out of various options, for determining relevance, while specificity of the search request, task, or retrieved results also helps greatly in relevance judgment. Research limitations/implications - Relevance research should focus on the topicality and specificity of what is being evaluated as well as conducted in real environments. Practical implications - If multiple relevance factors are presented to assessors, the total number in a list should be below ten to take account of the limited processing capacity of human beings' short-term memory. Otherwise, the assessors might either completely ignore or inadequately consider some of the relevance factors when making judgment decisions. Originality/value - This study presents a method for reducing the artificiality of relevance research design, an apparent limitation in many related studies. Specifically, relevance judgment was made in this research as part of the 2007 TREC Legal track interactive task rather than a study devised for the sake of it. The assessors also served as searchers so that their searching experience would facilitate their subsequent relevance judgments.

Abstract

Wikipedia is increasingly an important source of information for many. Hence, it is important to develop an understanding of how it is situated within society and the wider roles it is called onto perform. This article argues that one of these roles is as a depository of collective memory. Building on the work of Pentzold, I present a case study of the English Wikipedia article on the Vietnam War to demonstrate that the article, or more accurately, its talk pages, provide a forum for the contestation of collective memory. I further argue that this function is one that should be supported by libraries as they position themselves within a rapidly changing digital world.

Abstract

Are art and science separated by an unbridgeable divide? Can they find common ground? In this new book, neuroscientist Eric R. Kandel, whose remarkable scientific career and deep interest in art give him a unique perspective, demonstrates how science can inform the way we experience a work of art and seek to understand its meaning. Kandel illustrates how reductionism?the distillation of larger scientific or aesthetic concepts into smaller, more tractable components?has been used by scientists and artists alike to pursue their respective truths. He draws on his Nobel Prize-winning work revealing the neurobiological underpinnings of learning and memory in sea slugs to shed light on the complex workings of the mental processes of higher animals. In Reductionism in Art and Brain Science, Kandel shows how this radically reductionist approach, applied to the most complex puzzle of our time?the brain?has been employed by modern artists who distill their subjective world into color, form, and light. Kandel demonstrates through bottom-up sensory and top-down cognitive functions how science can explore the complexities of human perception and help us to perceive, appreciate, and understand great works of art. At the heart of the book is an elegant elucidation of the contribution of reductionism to the evolution of modern art and its role in a monumental shift in artistic perspective. Reductionism steered the transition from figurative art to the first explorations of abstract art reflected in the works of Turner, Monet, Kandinsky, Schoenberg, and Mondrian. Kandel explains how, in the postwar era, Pollock, de Kooning, Rothko, Louis, Turrell, and Flavin used a reductionist approach to arrive at their abstract expressionism and how Katz, Warhol, Close, and Sandback built upon the advances of the New York School to reimagine figurative and minimal art. Featuring captivating drawings of the brain alongside full-color reproductions of modern art masterpieces, this book draws out the common concerns of science and art and how they illuminate each other.

Abstract

As the number of scientific journals has multiplied, journal rankings have become increasingly important for scientific decisions. From submissions and subscriptions to grants and hirings, researchers, policy makers, and funding agencies make important decisions influenced by journal rankings such as the ISI journal impact factor. Typically, the rankings are derived from the citation network between a selection of journals and unavoidably depend on this selection. However, little is known about how robust rankings are to the selection of included journals. We compare the robustness of three journal rankings based on network flows induced on citation networks. They model pathways of researchers navigating the scholarly literature, stepping between journals and remembering their previous steps to different degrees: zero-step memory as impact factor, one-step memory as Eigenfactor, and two-step memory, corresponding to zero-, first-, and second-order Markov models of citation flow between journals. We conclude that higher-order Markov models perform better and are more robust to the selection of journals. Whereas our analysis indicates that higher-order models perform better, the performance gain for higher-order Markov models comes at the cost of requiring more citation data over a longer time period.

Abstract

We study how collective memories are formed online. We do so by tracking entities that emerge in public discourse, that is, in online text streams such as social media and news streams, before they are incorporated into Wikipedia, which, we argue, can be viewed as an online place for collective memory. By tracking how entities emerge in public discourse, that is, the temporal patterns between their first mention in online text streams and subsequent incorporation into collective memory, we gain insights into how the collective remembrance process happens online. Specifically, we analyze nearly 80,000 entities as they emerge in online text streams before they are incorporated into Wikipedia. The online text streams we use for our analysis comprise of social media and news streams, and span over 579 million documents in a time span of 18 months. We discover two main emergence patterns: entities that emerge in a "bursty" fashion, that is, that appear in public discourse without a precedent, blast into activity and transition into collective memory. Other entities display a "delayed" pattern, where they appear in public discourse, experience a period of inactivity, and then resurface before transitioning into our cultural collective memory.

Abstract

A framework is developed that supports the theoretical design of an organizational memory information system (OMIS). The framework provides guidance for managing the processing capabilities of an organization by matching knowledge location, flexibility, and processing requirements with data architecture. This framework is tested using three different sets of data attributes and data architectures from 147 business professionals that have experience in IS development. We find that trade-offs exist between the amount of knowledge embedded in the data architecture and the flexibility of data architectures. This trade-off is contingent on the characteristics of the set of tasks that the data architecture is being designed to support. Further, the match is important to consider in the design of OMIS database architecture.

Abstract

Primitive thinking forms affected the organization of knowledge, and at a later date writing also affected organization. Currently, the web requires new forms of learning and knowledge; with the globalization of information, connectivity and virtuality have a bearing on human thought. Digital thinking is shaping our reality and its organizational form. Natural memory, considered to be a process that requires the structure of natural language and human capabilities, is interwoven with a subject and a conscience; memory preserved through writing required other tools to assist it, and classifications, cataloguing, organization or other KOS were created. The new tool for recovering digital memory is the semantic web. This points to information's future on the Internet and seems to approach the utopia of global, organized information and attempts to give the website greater significance. The Web 3.0 incorporates a proliferation of languages, concepts and tools that are difficult to govern and are created by users. The semantic web seems to be a natural evolution of the participative web in which we find ourselves, and if an effective combination is achieved between the inclusion of semantic content in web pages and the use of artificial intelligence it will be a revolution; semantic codification will be a fact when it is totally automated. Based on this, a collective digital intelligence is being constituted. We find ourselves before intelligent multitudes with broad access to enormous amounts of information. The intelligent multitude emerges when technologies interconnect. In this global interconnection of semantic information an exponential pattern of technological growth can take place.

Abstract

Large corpora are ubiquitous in today's world and memory quickly becomes the limiting factor in practical applications of the Vector Space Model (VSM). In this paper, we identify a gap in existing implementations of many of the popular algorithms, which is their scalability and ease of use. We describe a Natural Language Processing software framework which is based on the idea of document streaming, i.e. processing corpora document after document, in a memory independent fashion. Within this framework, we implement several popular algorithms for topical inference, including Latent Semantic Analysis and Latent Dirichlet Allocation, in a way that makes them completely independent of the training corpus size. Particular emphasis is placed on straightforward and intuitive framework design, so that modifications and extensions of the methods and/or their application by interested practitioners are effortless. We demonstrate the usefulness of our approach on a real-world scenario of computing document similarities within an existing digital library DML-CZ.

Abstract

Many memory institutions are now digitizing their holdings to provide online access. Although recent developments in technology have allowed users to create high quality digital resources outside institutional boundaries, little consideration has been given to the potential contribution that the general public can make to digitizing cultural heritage. This article seeks to scope the growing trend of the creation of digital images of cultural and heritage materials beyond library, art gallery, or museum walls, particularly focusing on the use of the image-hosting site Flickr (www.flickr.com) as a forum for hosting, discussing, and collecting vintage ephemera. This article discusses how Flickr is currently being used and provides empirical data that demonstrates that the most successful examples of this approach can teach best practice to traditional memory institutions in how to make their collections useful, interesting, and used by online communities. The use of a common, centralized access point to image-based heritage allows a central point for discussing and accessing collections. Furthermore, the adoption of Flickr by libraries and archives can extend the use of collections and the interaction that this affords both the institution and the individual.
